REGULATlNG slGHT-FEED OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 276,069, dated April1'7, 1883.

Application led September 28, 1882. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM RPHILLIPS, of Cambridge, in the county ofMiddlesex and State of Massachusetts, a citizen of the United States,have invented a new and useful lmprovementin Regulating Sight-FeedOil-Cu ps, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawing. v

This invention relates to the class of oilcups used upon machinery andengines, consisting of a base having an opening near the bottom, throughwhich can be seen the-oil from thelubrieator as it is dropped from aboveonto the portion to be lubricated, and having a body or reservoir forthe oil above the base, with a device for regulating the flow of theoil.

My present invention is an improvement upon my regulating sight-feedoil-cup the application for patent upon which was tiled inv the PatentOtlice March 13, 1882.

In the drawing the figure represents an upright center crosssection ofthe oil-cup, in which A is the body; B, the base; C, the upright-stein;D, a check-nut, and E the sightopening in the base.

ln this invention l have produced an oilcup which has an upright centralspindle or stem, upon the lower end ot' which is formed a valve throughwhich the oil passes in a downward direction to the point to belubricated. The bodyot' the cup Ais preferable glass, and is providedwith a metal cover, a, which is made to rest upon the top, and having anaperture in the center through which passes the stem C. Over the top orcover c is placed a check-nut, D. The check-nut is provided with athreadwhich acts in connection with the thread upon the top of the stem,(represented by b). The bottom of the stem is tted into an opening madein the base B, and has a duct, y, for the passage of the oil downward,after entering through the valve, which is represented by X. Justbelowthe valve-seat au enlargement is made, (represented by X,) intowhich the oil tirst flows after passing the valve X. From X the oilpasses down the duct y, and into a duct made in the base, andrepresented by e, which duct is a continuation of the duct y, and whichcarries the oil to the upper part of the sight-feedopening E, throughwhich opening the oil drops from the shoulders z z' to the bearing. Thebottom of the stem below the valve X has an external thread, d.

A corresponding thread is cut to receive it in the base B. The top ofthe base B extends upward in the center, as represented byh, the betterto form the valve-connection with the stem, and also to prevent thesediment from the oil from interfering with the working of the valve X.The lower part of the body of thecap A tits over the projecting part ofthe base h, and is united With the cup by the collar or nut g, the slotsor recesses g being made to receive the wrench or other suitable toolfor the purpose of turning the said collar or nut. The projecting partof the base h is threaded externally. as shown by c, upon which thecollar or nut tits.

it will be observed that the stem can be raised and held in any desiredposition by means of' the threaded bottom d and the cheek-nut D. Thisconstruction is an improvenient over my former invention, in that thevalve-stem is operated from the top, and in the novelarrangement of thevalve, the duct, and the contiguous opening X', which facilitates theoperation of the oil-cup in practical use. Itis also a constructionwhich can be mannfactnrcd at a low price, and which cannot readily beclogged or get out of order.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent of the United States, is-

l. An oil-cup consisting of the body -A, with a cover, c, the centralvalve, X, and stem C, provided with check-nut D, and the base B,provided with the sight-feed opening E, and adapted to be secured to thebody A by the nut g, all substantially as and for the purposes setforth.

2. In a regulating sightfeed oil-cup, the base B, with perpendicularduct z, and sightopening E, in combination with a perpendicularvalve-stem, C, and valve X, and duct y, substantially as and for thepurposes set forth.

3. In an oil-cup, the perpendicular valvestem C, valve X, and duct y, incombination with the intermediate oil-reservoir, X', sub stantially asand for the purposes described.

4. In an oil-cup, the valve X and stem C, provided with the screw-threadb and screwthread d, in combination with the base B, and the check-nut Dand cover a, substantially as and for the purposes described.
